This figure summarizes the results of analyzing multiple occurrences of the same link within data sets. The intra-dataset confirmation rate is the number of tests for a link that were "successful", divided by the total number of tests for that link. For example, a link might be tested between two genes that have two probes representing them, each. This yields a total of four tests of correlation between the two genes. If two of these tests yielded links that passed our selection criteria, the intra-dataset confirmation rate is 0.5
As this graph makes clear, most intra-dataset confirmation rates are low.
